Just for clarification, the wx.SetDefaultPyEncoding value only sets the 
codec to be used when wxPython needs to convert to/from unicode/ansi for 
wx methods and functions only.  This value usually defaults to 
locale.getpreferredencoding() so it matches what Python thinks is the 
default for your system as it is currently configured.  It doesn't have 
any effect on any other automatic conversions or coercions that Python 
will try to.

For example, if you have a Unicode build of wxPython, and pass a string 
object to textctrl.SetValue, then it will use the 
wx.GetDefaultPyEncoding() encoding to convert it to a Unicode object to 
pass to the C++ SetValue.  The opposite is also true, if you have an 
ansi build of wxPython and pass a Unicode object then that encoding will 
be used to convert it to a string first.

For other automatic ansi/unicode conversions that Python does then it 
uses the return value of sys.getdefaultencoding() for the encoding. 
Python also provides the sys.getfilesystemencoding() value which 
specifies what should be used for encoding unicode values into ansi 
strings to be used for path and file names on the current system.
